It includes a catheter tube and a needle. Generally, an eyelet ring is inserted into the catheter.
Such a catheter tube is inserted integrally with the eyelet ring into an opening in the nose portion of the hub and secured to the hub by pressing the eyelet ring into the nose portion of the hub. Thereafter, the hub and catheter tube assembly is attached around a sharp needle, which is further attached to a plastic hub. The sharp tip of the needle pierces a vessel in the body to allow access of the needle and subsequent catheter tube into the body lumen. As the catheter tube and needle enter the body lumen, the needle is removed and discarded, while only the catheter tube remains in the body lumen. Thereafter, a syringe or infusion tube is attached to the hub to allow fluid to flow between the infusion device or syringe and the body lumen via the hub and the catheter. Generally, the hub is formed of a material that provides sufficient rigidity to secure and attach the drip tube, and the catheter tube is typically formed of a soft, soft material to minimize damage to the body. ing.

組立体が要望されている。A cover can be used with an inner shield to cover the needle to prevent accidental piercing of the healthcare worker's skin with the sharp tip of a used needle. . U.S. Pat. No. 5,344,408 issued to Partika (Partika) discloses an example of an apparatus used in the art. That is, in Partika, the lever and the teeth fix the needle so that the needle does not protrude from the housing. More specifically, one lever arm has a hole for receiving a needle, and the distal end of the lever arm is configured to contact the inner surface of the housing. However, the assembly is not stable because the lever arm contacts the assembly at only one point. That is, such an assembly may disengage when force is applied to the proximal end of the lever arm. Therefore, there is a need for an assembly that can increase the stability of the needle in the housing to prevent such assembly displacement.

Includes a housing 15, a needle 45, and a member 20. The housing 15 has a proximal end and a distal end. Further, the housing 15 has opposing surfaces connected to the base end and the front end, respectively. The member 20 is constructed of a flexible material, such as a stainless steel shunt material, and is bent by various methods including the use of a die to press the member 20 into the member 2.
Various point angles at zero can be formed. The member 20 is angled in at least two positions. These angles can range from about 20 ° to 90 °. 1 and 2, the angled position of the member 20 is the first contact position 30 and the second contact position 4.
Indicated by 0. Thus, by providing the first contact position 30 and the second contact position 40 at different positions on the inner surface of the housing 15, an example of the embodiment of the present invention inserts the needle 45 into the patient's body. It is believed that the stability of securing and holding the needle 45 before, during, and after insertion can be increased. in addition,
In addition to the first contact position and the second contact position (30, 40), a third contact position 25 and a fourth contact position 35
Is provided between the member 20 and the housing 15,
The stability of fixing and holding the needle 45 can be further improved.

Although the hole 42 is shown generally at the center of the member 20, it will be appreciated that other configurations are also effective in practicing the present invention. For example, the member 20 is configured to have a plurality of inclined portions,
The member 20 can have a location for receiving more than one needle 45.

The needle 45 is in this unlocked position during insertion of the needle 45 into the patient's body and while the needle 45 is in the patient's body. The distal end and the proximal end of the member 20 extend in the lateral direction with respect to the member 20. When the distal end of the member 20 is in the vicinity of the member 20, the needle 45
It is movable within the 0 hole 100.

As the needle 45 is removed from the patient and the catheter (not shown), the distal end of the member 20 contacts the beveled distal end of the needle 45 that has slipped out of the catheter (not shown). In this way,
When the tip of the member 20 contacts the inclined tip of the needle 45, a click sound or a snap sound is generated. The sound indicates to the healthcare provider that the needle 45 has been secured in the housing 15 and indicates that the used needle is now safe from accidental piercing of the skin.

Although the hole 100 is shown having a generally circular upper portion and a generally oval lower portion, other shapes may be employed. For example, hole 100 can be any suitable shape for securely holding member 20, such as a circle, square, oval, and the like. Needle 45 slides through a large portion of this hole 100 when in the unlocked position shown in FIGS.

The distal end of 40 has a first concave area 105 and the second arm 125 has a second concave area 110. These concave areas are sometimes referred to as depressions,
Of the housing 15 or the inner surface of the housing 15. The member 20 is generally longer than the housing 15 and is configured such that when forcibly matching the dimensions inside the housing 15, tension is generated in the member 20 to increase the pressing force on the housing 15.

However, even if the distal end side force is continuously applied to the member 20 after the member 20 is locked together with the needle 45, the needle 45 does not advance any further.
Thus, the present invention can provide advantages over the prior art because the force required to cause the device to misalign is large enough to destroy the entire device.
